Red Team Performance: Summary of Findings
(2004-06)This report summarizes a study the performance of the red team program at Sandia National Laboratories. This study describes the factors that contribute to and hinder red team performance, as well as various measures of ... -
Redesigning the Introductory Statistics Course
(1995)There is general agreement that the traditional statistics course does not meet the needs of customer groups such as students and their future employers. While positive reform efforts are under way, many appear to be based ... -
Reducing Workload and Increasing Patient Safety Through Work and Workspace Design
(2003-11)This paper was commissioned by the Institute of Medicine Committee on the Work Environment for Nurses and Patient Safety. It was used by the IOM for its report on Keeping Patients Safe - Transforming the Work Environment ... -
Retargeting Higher Education Access and Persistence Efforts: Illustrating a 'System' Focused Process for Improving Public Policy
(1999-07)This paper illustrates a "systems" approach, based on the quality function deployment model, to examine both the direct and interaction effects of multiple solutions aimed at improving access and persistence. -
Robust Product Designs, Part I: First-Order Models with Design x Environment Interactions
(1990)In this paper we apply the strategy developed in Report 56 to a simple first-order model with interactions between the design and the environmental factors. For this model we derive the robustness measure and give a series ... -
Robust Product Designs, Part II: Second-Order Models
(1990-05)In this paper we apply the strategy developed in Report 56 to a general second-order model. For this model we derive the robustness measure and give a series of tables of designs that are appropriate for the possible ... -
Robust Product Designs, Part III: Second-Order Models with Additional Third-Order Terms
(1990-05)In this paper we apply the strategy developed in Report 56 to a general second-order model with additional third-order terms. For this model we derive the robustness measure and give a series of tables of designs that are ... -
The Role of Scientific Problem Solving and Statistics in Quality Improvement: Some Perspectives
(1997-04)Scientific method of observation and experimentation play a key role in quality improvement. In this article, I provide numerous examples of the use of scientific method and argue that this a vital catalyst for Total ... -
Role of Statistics in Quality Control
(1993-06)The role of Statistics in Quality Systems depends on certain philosophical issues which the author believes have been inadequately addressed. Three such issues are the role of statistics in the process of discovery, the ... -
Scientific Statistics, Teaching, Learning and the Computer
(1996-06)It is argued that the domination of Statistics by Mathematics rather than by Science has greatly reduced the value and the status of the subject. The mathematical "theorem - proof paradigm" has supplanted the "iterative ... -
Sequential Methods in Statistical Process Monitoring, Chapter 1: Introduction and Chapter 2: Sequential Monitoring of Variances
(1991-05)A CUSUM chart to monitor variability, based on the Wald-Barnard likelihood ratio test, is introduced. A nomogram to aid in the construction of the charts is also presented. -
Sequential Methods in Statistical Process Monitoring, Chapter 3: Design of CUSUM Charts
(1991-05)In this report we show how to design CUSUM charts to monitor process variability. An eight step outline for the implementation of these charts is included. -
Sequential Methods in Statistical Process Monitoring, Chapter 4: Sequential Monitoring of Models, Chapter 5: Summary and Future Research, and Appendix: Table of ARL Values
(1991-05)An extension of the cumulative sum charts based on the Fisher's score function is introduced. This CUSCORE can be used to monitor parameter changes in a model. It is shown that the traditional CUSUM for location is a ... -
A Simple Rule for Judging Compliance Using Highly Censored Samples
(1991-04)A special case of judging compliance is when the effluent limit is set at a level below the method limit of detection (MDL) of the substance being monitored. In many such cases, almost all measurements on the effluent are ... -
Split-Plots for Robust Product and Process Experimentation
(2000-04)Environmentally robust products and processes are designed to be insensitive to variation over the relevant ranges of the environmental conditions in which they need to operate. Split plots frequently provide efficient ... -
Statistical Process Control and Automatic Process Control: A Discussion
(1992)The roles of Statistical Process Control for process monitoring and of Automatic Process Control for process regulation are considered and common misunderstandings discussed. Simple examples are used to show how the ... -
Statistics as a Catalyst to Learning
(1999-06)A discussion on Part I (Box and Liu, 1999) concerning the implications reaised when RSM is considered, as was originally intended as a statistical technique for the catalysis of iterative learning in the manner illustrated. -
Statistics for Discovery
(2002-03)In this paper the question is discussed why investigators in engineering and the physical sciences rarely use statistics. It is argued that statistics has been overly influenced by mathematical methods rather than the ... -
Studies in Quality Improvement: Designing Environmental Regulations
(1986-02)There is a surprising similarity between what SPC provides for industries and the need for constructing sensitive, reliable standards for environmental regulations. -
Studies in Quality Improvement: Minimizing Transmitted Variation by Parameter Design
(1986-02)By properly designing products and taking the inevitable variation in components into account, engineers can minimize the amount of variation that ultimately shows up in finished products.
